What do you call the purple gas that fills the test tube when a few crystals of iodine is being heated inside a test tube?
This is also iodine, as a gas.
What gas is produced when CaCO3 is heated?
A fart is created when CaCO3 is heated
How does iodine crystal changes into vapours?
Iodine sublimes- i.e it changes from solid to gas without going though a liquid phase.
What are produced when ammonium nitrate is heated?
water + amonia gas
Which compound should be heated with soda lime to obtain ethane gas in the laboratory its equation?
Sodium propanoate (or propionate) when heated with soda lime ethane gas is produced.
What is a solid purple-black non metal which changes to a deep purple gas when heated?
Iodine is a purple-black non metal that changes to a deep purple gas when heated.
Why can gas iodine stick to fingerprints?
The gas iodine will stick to the fingerprints because they will crystallize when they come into contact with a cool surface. When heated, iodine directly changes into vapor.

A fart is created when CaCO3 is heated
Why does iodine emit a purple gas when heated?
Because iodine sublimates, as do the other solid halogens. That means they go from solid to gas without becoming a liquid first.
When iodine is heated?
when iodine is heated it gives voilet vapours
When iodine is heated does any iodine melt?
iodine is a substance that has an unusual property, it has the ability to sublimate, this means that it converts directly from a solid to a gas with no liquid stage at all. So no, no iodine will "melt" into a liquid, it will insted turn into a purple gas.
When calcium carbonate is heated what gas is given off?
carbon dioxide is produced when it is heated
Does iodine create a gas when heated?
YES. it goes directly from the solid, crystalline state to a gas. This process is called sublimation.
Why is liquid iodine not visible if crystals are heated in the open air?
Because Iodine, like Carbon dioxide, sublimes straight from a solid to a gas and does not have a liquid phase.
How does iodine crystal changes into vapours?
Iodine sublimes- i.e it changes from solid to gas without going though a liquid phase.
